Disorders of Volume: Core Curriculum 2025.

Historically, the paradigm for all maladies was associated with an imbalance of the 4 humors: blood, black bile, yellow bile, and phlegm. Although our understanding of disease has evolved significantly since the time of Hippocrates, a similar cornerstone of inpatient and ambulatory care involves understanding and correcting imbalances of volume. The kidneys are the principal organs controlling extracellular volume, capable of both sensing and altering salt retention through multiple redundant pathways, including the sympathetic nervous system and the renin-angiotensin-aldosterone system.

Uncovering genetic signatures of the Walser migration in the Alps: Patterns of diversity and differentiation.

Since leaving Africa, human populations have gone through a series of range expansions. While the genomic signatures of these expansions are well detectable on a continental scale, the genomic consequences of small-scale expansions over shorter time spans are more challenging to disentangle. The medieval migration of the Walser people from their homeland in ssouthern Switzerland (Upper Valais) into other regions of the Alps is a good example of such a comparatively recent geographic and demographic expansion in humans.

A Self-Adjuvanting Large Pore 2D Covalent Organic Framework as a Vaccine Platform.

Vaccines are one of the greatest human achievements in public health, as they help prevent the spread of diseases, reduce illness and death rates, saving thousands of lives with few side effects. Traditional vaccine development is centered around using live attenuated or inactivated pathogens, which is expensive and has resulted in vaccine-associated illnesses. Advancements have led to the development of safer subunit vaccines, which contain recombinant proteins isolated from pathogens.

Resident and supervisor perceptions of gaining obstetrical competency in Family Medicine: a qualitative descriptive study.

Introduction: Canadian Family Medicine (FM) residents, upon graduation, are disinclined to provide intrapartum care. The FM resident experience with obstetrical training has not been studied in over a decade while the FM landscape has changed. This study explored the FM resident experience in working towards their obstetrical competencies as one of the chief influences on their career decision to provide intrapartum care or not.

A Comprehensive Review of Low-Dose Interleukin-2 (IL-2) Therapy for Systemic Lupus Erythematosus: Mechanisms, Efficacy, and Clinical Applications.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that causes extensive inflammation and tissue destruction across several organs. Conventional therapies, such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and immunosuppressive drugs, can have serious adverse effects and are not always successful. This study looks at the possibility of low-dose interleukin-2 (IL-2) therapy as a new treatment for SLE, focusing on its mechanics, effectiveness, and clinical applicability.

Association Between the Immune Checkpoint Inhibitor Durvalumab and Myasthenia Gravis: A Comprehensive Review.

Immune checkpoint inhibitors (ICIs), including Imfinzi (durvalumab), have revolutionized cancer treatment by stimulating the body's immune system to target cancerous cells. Although pharmaceuticals offer therapeutic benefits, several drugs have been associated with immune-related adverse events (irAEs), including the uncommon but serious condition known as myasthenia gravis (MG). This review synthesizes data from pertinent research to offer a thorough evaluation of the literature on the underlying mechanisms, clinical manifestations, and therapeutic approaches for durvalumab-induced MG.

Efficacy of Posterior Pharyngeal Wall Injection for Velopharyngeal Dysfunction in Adults.

Objective(s): Posterior pharyngeal wall (PPW) injection is often employed to treat velopharyngeal deficiency (VPD). We sought to analyze the impact of PPW injection on severity of dysphagia and dysphonia.

Methods: Retrospective chart review was conducted of patients undergoing PPW injection from 2018 to 2023 at a tertiary laryngology center.

Molecular docking analysis of shatavarins with female hormonal receptors.

Shatavari () has been used for female health problems since ancient times and is useful for treating various female reproductive problems including menopausal problems, hormonal imbalance, lactation, menstrual issues, and others. Shatavarins, the primary phytoconstituents of Shatavari, have high molecular weights and may interact with hormone receptors. We have conducted a molecular docking analysis for different Shatavarins such as Shatavarin I, Shatavarin IV, Shatavarin VI, Shatavarin VII, Shatavarin VIII, Shatavarin IX, and Shatavarin X with different hormonal receptors such as estrogen alpha, beta, and gamma receptor, progesterone receptor, FSH, and LH receptors.

Strengthening facility-based integrated emergency care services for time sensitive emergencies at all levels of healthcare in India: An implementation research study protocol.

Predictors for success and failure in international medical graduates: a systematic review of observational studies.

Background: International Medical Graduates (IMG) are an essential part of the international physician workforce, and exploring the predictors of success and failure for IMGs could help inform international and national physician labour workforce selection and planning. The objective of this study was to explore predictors for success for selection of IMGs into high stakes postgraduate training positions and practice and not necessarily for informing IMGs.

Methods: We searched 11 databases, including Medline, Embase and LILACS, from inception to February 2022 for studies that explored the predictors of success and failure in IMGs.

Antifungal metabolites produced by Pseudomonas hunanensis SPT26 effective in biocontrol of fusarium wilt of Lycopersicum esculentum under saline conditions.

In past few years, salinity has become one of the important abiotic stresses in the agricultural fields due to anthropogenic activities. Salinity is leading towards yield losses due to soil infertility and increasing vulnerability of crops to diseases. Fluorescent pseudomonads are a diverse group of soil microorganisms known for promoting plant growth by involving various traits including protecting crops from infection by the phytopathogens.

An Atypical Presentation of Molluscum Contagiosum in a Newborn.

Molluscum contagiosum (MC) is a skin infection caused by a poxvirus that is highly contagious and common among children. When MC does occur in children less than one year old, it is suspected to be a result of vertical transmission through maternal MC infection. In this report, we describe a case of MC on the scalp of a 10-month-old child that started shortly after birth via Cesarean delivery.

Objective: To investigate whether social distancing during the pandemic was associated with a higher neonatal mortality rate.

De-novo ATR-16 syndrome associated with inherited hemoglobin Evanston causing HbH phenotype: a rare occurrence.

Abnormality of three α-globin genes, either deletion or point mutation results in symptomatic Hemoglobin H (HbH) phenotype. Most of such cases of α-globin defects are inherited from the parents, de-novo cases are exceedingly rare. Herein, a case of HbH is reported where the proband inherited one α-globin gene with a point mutation (α) from the mother.

Identification of an H-Ras nanocluster disrupting peptide.

Hyperactive Ras signalling is found in most cancers. Ras proteins are only active in membrane nanoclusters, which are therefore potential drug targets. We previously showed that the nanocluster scaffold galectin-1 (Gal1) enhances H-Ras nanoclustering via direct interaction with the Ras binding domain (RBD) of Raf.
